A state wants to build a light rail system between two cities. It purchases most of the land needed for the system, but one family refuses to sell its property to the state. What can the state do? The state can file a civil law case with the Supreme Court to get the land.

The state will ask the federal government to handle the negotiations with the family.

There is nothing the state can do and the plans for the light rail system will not proceed.

The state has the authority through eminent domain to take the land if it is necessary for the general public.
